Dielectric and impedance study of ‘Ca’-doped BaFe0.5Nb0.5O3 complex perovskite
Source abstract
Abstract
This paper reports the synthesis of Ba0.92Ca0.08Fe0.5Nb0.5O3 ceramics and its structural, dielectric, and electrical characteristics. Preliminary structural analysis through X-ray diffraction suggests the single-phase monoclinic crystal symmetry of the sample. Its quality is asserted by microstructural and elemental studies carried out by scanning electron microscopy and energy-dispersive X-ray spectroscopy techniques, respectively. Detailed examination of dielectric and electrical parameters in wide temperature (15–300 °C) and frequency (100–500 kHz) ranges reveals many interesting results that correlate structure with observed characteristics. The complex impedance plots confer the temperature-reliant nature of grain and grain boundary effect.
